As some of you know (probably all of you do by now, LOL!!) I'm RBE sensitive on white over dark. I've got an HD70 that I love but will probably be upgrading this summer. My hopes for a 720p LED DLP is dashed as there is nothing in sight, so I was thinking of picking up a used HD80 or something.

Now, I'm hearing conflicting opinions on what exactly is a 6x wheel. Some say it spins at its 6x no matter what and others say, it runs at about 4x-5x regularly while using 6x in high altitude mode or when the lamp is set to high. Can someone clarify this for me? Thx.

I was hoping Optoma would replace the HD65 in 2009 with a 6x model, but NOOOO!!! All just to spite ME!!

Lamp brightness, under any conceivable way, should not affect the color wheel speed. High altitude mode should only affect the fans, which need to blow harder due to less air density, which should in no way affect the color wheel.
The only thing that can affect the color wheel speed, is the refresh rate of the input signal. Some projectors sync the color wheel to the refresh rate. For example, i can hear my color wheel actually slow down when i change my refresh from 60 to 48 hz.
